【Abstract】 The bentonite that was activated by microwave heating was used as adsorbent to treat Cu 2+ wastewater. The effect on the adsorption of Cu 2+ in bentonite of microwave heating time, dose of bentonite, oscilation adsorption time, intial Cu 2+ conentration in wastewater, pH etc. was studied. The results showed that microwave heating can activate bentonite, leading to satisfactory adsorption effect. Compared with the heating activation by Muffle oven, the microwave heating activation technology is simpler and the activation time can be greatly shortened, leading to an enormous saving in activation needed energy.更多还原
